What is the test for dismissing one or more strikes 3?

Accordingly, although we shall affirm the judgment, we shall remand the matter to the trial court so it may determine whether or not to exercise its limited discretion. (People v. Superior Court (Romero), supra, 13 Cal.4th 497, 528-533, 53 Cal.Rptr.2d 789, 917 P.2d 628.) If it decides not to exercise its limited discretion, the defendant need not be present and the imposed sentence shall remain in effect. However, if the trial court believes it would not be an abuse of its limited discretion to dismiss one or more "strikes" ³--and it wishes to do so--then the defendant must be present and a new sentence hearing conducted.
